CATransition *animation = [CATransitionanimation];
[animation setType:kCATransitionFade];
[animation setSubtype:kCATransitionFromTop];
[animation setDelegate:self];
[hearingAidHalosetBackgroundImage:[UIImageimageNamed:@"m13_grayglow.png"]forState:UIControlStateNormal];
[animation setDuration:2.0];
[animation setValue:@"Throb"forKey:@"MyAnimationType"];
[[hearingAidHalolayer] addAnimation:animation forKey:nil];
 
- (void)animationDidStop:(CAAnimation *)theAnimationfinished:(BOOL)flag{
 
    NSString* value = [theAnimationvalueForKey:@"MyAnimationType"];
    if([value isEqualToString:@"Throb"])
    {
       //... Your code here ...
       return;
    }
 
    if([value isEqualToString:@"Special1"])
    {
       //... Your code here ...
       return;
    }
 
    //Add any future keyed animation operations when the animations are stopped.
}

2.CAAnimationGroup

Important: The delegate and removedOnCompletion properties of animations in the animations array are currently ignored. The CAAnimationGroup delegate does receive these messages.

3.要让一个ca动画终止后，保留末状态，在设置removedOnCompletion = NO后，还得设置fillMode = kCA…..Forward 这个宏名字不太记得了。。。
